Water is boiled in a 1-l coffee maker with an immersion-type electric heating element at atmospheric pressure. it was observed that ½-l has evaporated in 13 min once boiling starts. a) if the heating element is rated based on power required to evaporate water, determine the rating of the heating element. b) for the same heating element, how long will it take to raise the 1-l temperature from 18 oc to boiling point at the same atmospheric pressure? take liquid water density air = 1000 kg/m3 & specific heat cpwater = 4.18 kj/(kg. ok).
